* Remove the 'opal_mca_base_param_use_amca_sets' global variable * Harness the fact that you can (read should) call the cmd_line functions before initializing opal_init_util(). This pushes the MCA/GMCA/AMCA command line options into the environment before OPAL inits and starts to use these values. By putting the cmd_line parse before opal_init_util in orterun and orted we only parse the *MCA parameter files once, and correctly (alleviating the need to 'recache' the files on init.) * Small bits of cleanup. This commit was SVN r15219.
